}

if (@unlink($this->root . "files" . $folderPath . SEP . $infoFile["file_name"])) {

query($q);

$q = "OPTIMIZE TABLE " . TABLE_PREFIX . "files";
query($q);

$this->updateFolderSize($infoFile["id_folder"], $infoFile["file_size"], "-");
$this->updateFolderTime($infoFile["id_folder"]);
return true;
}
return false;
}

use code tags - it's v difficult to follow.

1) Is

$this->root . "files" . $folderPath . SEP . $infoFile["file_name"]

pointing to the file correctly (no problems with path / filename)?

2) Replace @unlink with unlink -> @ symbol suppresses errors, you might wanna see all the errors while debugging
